PRIMARY LEIOMYOSARCOMA OF THE THYROID-GLAND

Primary leiomyosarcoma of the thyroid gland is extremely rare, and to the best of our knowledge only five well-documented cases have been re ported in the world literature. We herein report a 58-year-old female patient with primary leiomyosarcoma of the thyroid who was successfull y treated by total thyroidectomy with a modified neck dissection. Immu nohistochemically, the tumor cells showed positive reactivity to alpha -smooth muscle actin and vimentin, Radical surgery was thus considered to be essential in the treatment of this rare but rather aggressive m alignancy.
